Hi Sarah,
I take it you wanted feedback on both the site and the product - in which case, here's a bit of constructive criticism on the site itself:
It's a shame the look & feel of the product catalogue doesn't more closely match that of the main site. I guess that's as a result of using a 3rd party shop solution.
The front page of the online shop contained a load of error messages, as the PC I am using at the moment does not have v8 of the Macromedia Flash player installed.
On the Special Offers page and the Artwork page none of the pictures displays.
The left menu only appears on the home page, so on all other pages you have to use the Back button to go anywhere else.
Hope this helps,
Dave.
